Ellipticine quinone, also known as NSC-383230, is a Drp1 inhibitor. rpitor1 and Drpitor1a inhibited the GTPase activity of Drp1 without inhibiting the GTPase of dynamin 1. Ellipticine quinone showed greater potency than the current std. Drp1 GTPase inhibitor, mdivi-1, (IC50 for mitochondrial fragmentation are (0.06, and 10 μM, resp.). Ellipticine quinone suppressed lung cancer tumor growth in a mouse xenograft model. Ellipticine quinone also inhibited mitochondrial ROS prodn., prevented mitochondrial fission, and improved right ventricular diastolic dysfunction during IR injury.
9-Methoxyellipticine is an alkaloid and a derivative of the DNA intercalating agent ellipticine that has been found in O. maculataand has anticancer activity.It intercalates into DNA and is an inhibitor of wild-type c-Kit and c-Kit containing the D816V activating mutation (c-KitD816V; IC50s = 0.8 and 0.6 μM, respectively).
Hydroxyellipticine-1a, a selective r(CGG)exp probe, improves pre-mRNA splicing defects, inhibits formation of nuclear inclusions and RANT in a FXTAS cellular mode.l
K34c is a potent and selective α5β1 integrin inhibitor (IC50 = 3.1 nM). K34c inhibits cell survival and migration, inhibits p53-dependent senescence induced by Temozolomide or Ellipticine and promotes apoptosis in U87MG cells. K34c also prevents TGFβ-induced infiltrationin vivoand reduces cell adhesion on fibronectin.
